Here is a tip for bifold cabinet doors
I have seen this way too much. It is something that no one hardly ever thinks about and gets missed just about every time.
Lazy susan corner cabinet. Double door, hinges between the two. Most know these as bifold doors.
When the door knob or handle goes on, recess the head of the screw on the back side of the handle or knob.
The reason is that just about everyone, including myself, is lazy. The door will eventually be closed in a way that hits the adjacent door (if there is one) or appliance, leaving an oh so beautiful scratch or gouge right across the face. This will also happen to the face frame if the little rubber bumper drops off.
Which reminds me, don't buy the rubber bumpers at Home Depot. They fall off.
